I've also been using my Cricut to design some t-shirts.
The first one was a cassette tape for my son. I saw it on an adult shirt and thought it would be funny for him because he never even saw one for real.
The cassette is from the Cricut cartridge "Indie Art" and I used hotfix glitter foil for the middle part. For the outer part I used regular cotton which I ironed on the shirt with steam-a-seam.
Later on my husband had a family day at work so I wanted to make my son a shirt with their logo on it. My son picked the colors and the guitar model. The Flying-V is from the Cricut Cartridge "Indie Art" and I used hotfix flock to iron onto the shirt. I downloaded the Gibson-logo from their website and used SCAL to cut it with my Expression.
And when I couldn't find a Pink Ladies jacket in the size of our bridesmaid I made her a Pink Ladies shirt myself. I downloaded the font American Pop One to cut it on my Expression with SCAL. I think it looked really cute.
But it all started out with this hotfix nailhead KISS logo I made for my son after a rhinestone shirt I once bought for myself at a KISS concert.
Next project is a shirt with the Incredibles logo on it, but I'm gonna wait till summer for that. Untill then I'll probably find lots of other stuff to fulfill my crafting needs with!
